Conceptual design of a fully passive transfemoral prosthesis to facilitate energy-efficient gait
Ünal, Ramazan; Behrens, S.; Carloni, R.; Hekman, E.; Stramigioli, S.; Koopman, B. (IEEE, 2018-12)In this paper, we present the working principle and conceptual design toward the realization of a fully-passive transfemoral prosthesis that mimics the energetics of the natural human gait. The fundamental property of the ... -
Design of bio-joint shaped knee exoskeleton assisting for walking and sit-to-stance
Kapci, M. F.; Ünal, Ramazan (Springer Nature, 2019)In this study, a bio-joint shaped knee joint exoskeleton is presented. This design is meant for avoiding misalignment of the exoskeleton joint with the biological knee joint. For this purpose a cam mechanism has been ... -
A soft+rigid hybrid exoskeleton concept in scissors-pendulum mode: A suit for human state sensing and an exoskeleton for assistance
Uğurlu, Regaip Barkan; Acer, M.; Barkana, D. E.; Gocek, I.; Kucukyilmaz, A.; Arslan, Y. Z.; Basturk, H.; Samur, E.; Ugur, E.; Ünal, Ramazan; Bebek, Özkan (IEEE, 2019-06)In this paper, we present a novel concept that can enable the human aware control of exoskeletons through the integration of a soft suit and a robotic exoskeleton. Unlike the state-of-the-art exoskeleton controllers which ...
